According to court documents filed on Nov. 27 in Houston, Texas, Sinopec USA claims that PDVSA has failed to pay for half of a $43.5 million order for steel products. The lawsuit was first reported by the Financial Times on Wednesday.

The disputed amount is small when compared to the massive debts Venezuela is struggling to repay.

Venezuela and PDVSA owe more than $60 billion just to bondholders. In total, the country owes $196 billion, according to a paper published by the Harvard Law Roundtable.

Paying Sinopec’s bill is far from the most pressing matter facing Venezuela.

The country is suffering a massive humanitarian crisis. There is a severe shortage of food and medicine. Many Venezuelans can’t buy basic items because prices are skyrocketing. The country’s currency, the bolivar, is worth less than a tenth of a U.S. penny, and the central bank has less than $10 billion left in reserves.
